<h2><a name="_description"></a>DESCRIPTION <a href="#_top"><img alt="^" border="0" src="../up.png"></a></h2>
<div class="fragment"><pre class="comment"> Convert ascii text to a binary image using pre-computed templates.

 Input strings can only contain standard characters (ascii character
 32-126). First time char2img() is ever called with a given height h,
 txt2img() is used to create a template for each ascii character. All
 subsequent calls to to char2img() with the given height are very fast as
 the pre-computed templates are used and no display/screen capture is
 needed.

 USAGE
  masks = char2img( strings, h, [pad] )

 INPUTS
  strings  - {1xn} text string or cell array of text strings to convert
  h        - font height in pixels
  pad      - [0] amount of extra padding between chars

 OUTPUTS
  masks    - {1xn} binary image masks of height h for each string

 EXAMPLE
  mask=char2img('hello world',50); im(mask{1})
  mask=char2img(num2str(pi),35); im(mask{1})
